I completely agree. As a sp I dont like being asked personal questions. I never lie about my life or personal likes/dislikes and so forth, I just don't freely give the information out. However if I have been seeing someone for a while and become more comfortable with them, I generally let my guard down a lil and share more about myself...
Somethings that I never will answer, nor do I like to have asked are, as stated above, "What is your real name?", and also "Can I see u outside this "hobby"?".
There are some things I like to keep private. :D
